To find x:
ON is parallel to LM
8x - 8 = 7x + 4
-7x -7x
1x - 8 = 4
+8 +8
1x = 12
--- ---
1 1
x = 12
8(12) - 8 = 7(12) + 4
96 - 8 = 84 + 4
88 = 88
------------------------------------
To find y:
NM is parallel to OL
x - 5 = 3y - 6
12 - 5 = 3y - 6
7 = 3y - 6
+6 +6
13 = 3y
--- ---
3 3
13/3 = y
Check:
12 - 5 = 3(13/3) - 6
7 = 13 - 6
7 = 7
1 mile is made up of 1760 yards.
If the library is 5 miles from the post office then the library is (5 x 1760) yards from the post office.
5 x 1760 = 8800
So the library is 8800 yards from the post office.
Hello there!
My best guess would be to plug in 5 into n.
So:
f (n) = 5n-2
f (5) = 5 (5) -2
f (5) = 25-2
f (5) = 23
This is my GUESS. I'm not sure how to do this problem (it's been a while since I've done this).
So PLEASE get a second opinion or ask a teacher!
Hope this helped!
